Question

Multiplying polynomials

Please look at the picture and these are the answers I can choose from a / 10x_14
B / 10x^2 + 31x -14
C 7x+5
D 10x+5

Answer 1

To multiply the polynomials (5x-2)(2x+7), we use the distributive property and combine like terms to get the answer 10x^2 + 31x - 14.

To multiply the polynomials (5x-2)(2x+7), we can use the distributive property.

We multiply each term in the first polynomial by each term in the second polynomial and then combine like terms.

Here's how we do it:

(5x-2)(2x+7) = 5x*2x + 5x*7 - 2*2x - 2*7

Simplifying further gives:

(5x-2)(2x+7) =
`10x^2 + 35x - 4x - 14`

Combining like terms gives the final answer:

(5x-2)(2x+7) =
`10x^2 + 31x - 14`
